UC218 UC220 UC305 UC306 Contact Seals Pillow Block Insert Bearing Sturdy GCR15 Ball Bearing For Industrial Applications
The outer spherical bearing is a special type of bearing that is designed with a spherical outer ring. The most notable feature of this design is that it allows the bearing to fit into a corresponding concave spherical surface of the bearing seat, providing automatic self-aligning function.
In situations where the shaft is deflected due to load or if the center line of the shaft and the bearing seat hole is relatively offset during installation, the bearing is still able to work within its self-aligning range. This ensures that the bearing operates optimally and avoids any negative influence from installation error or shaft deformation.
Primarily, the outer spherical bearing can bear both radial and axial combined loads. However, it is generally not recommended for bearing axial loads alone. Its structure mainly comprises of a spherical outer ring, inner ring, and rolling elements such as balls or rollers situated between them. These rolling elements roll between the inner and outer rings to decrease friction and transfer loads effectively.
Characteristics of Outer Spherical Bearings
Outer spherical bearings are known for their unique features that enable them to fit into a corresponding concave spherical surface of the bearing seat, which provides them with automatic self-aligning ability. Even when the shaft is deflected due to load or when the centerline of the shaft and bearing seat hole is offset, outer spherical bearings can work within their self-aligning range, avoiding installation errors or shaft deformation.
In terms of load bearing capacity, outer spherical bearings can withstand radial and axial combined loads, primarily dominated by radial loads. However, it is not advisable to use these bearings to bear axial loads during the design process.
Outer spherical bearings are designed with a double-layer seal that prevents dust and other particles from entering the channel. This feature ensures the stability of the bearing and extends its service life, especially in harsh industrial operating environments.
Outer spherical bearings come in different structural variations. They have a tapered inner hole with a ratio of 1:12 and require a tight sleeve to function properly. They also have top screws and eccentric sleeves, each with unique application scenarios and performance characteristics.
Outer spherical bearings have a wide range of applications in the industrial field, particularly in heavy-duty machinery, construction equipment, mining machinery, transmission equipment, and agricultural machinery, among others. In harsh working environments, such as high temperature, heavy load, and vibration, outer spherical bearings can still maintain their stability and provide exceptional performance.

Outer spherical bearings are used in a broad range of application scenarios across various industries. Their unique design and outstanding performance characteristics make them an essential component in different industrial fields. Here are the primary fields where outer spherical bearings find their use:
The use of outer spherical bearings is widespread in the automotive industry and is considered an indispensable part of vehicle manufacturing. They are used in vital components such as engines, transmissions, rear axles, and steering gears, and have the ability to withstand high-speed rotation, high temperature, high pressure, and high impact loads. This ensures the overall performance and safety of the vehicles.
Outer spherical bearings are also widely used in the aviation and aerospace fields, particularly in equipment such as aircraft engines, turbochargers, hydraulic pumps, and gyroscopes. These machines require bearings that are capable of enduring harsh environments and extreme loads while maintaining high performance. The exceptional qualities of outer spherical bearings make them a perfect fit for these applications.
In the agricultural machinery sector, outer spherical bearings are put to extensive use, such as tractors, harvesters, seeders, and other agricultural equipment. These machines need to withstand vibration, impact, and dust erosion for optimal performance. The durable structure of outer spherical bearings ensures the required stability and reliability of the equipment.
The field of industrial equipment also calls for the use of outer spherical bearings, such as CNC machine tools, robots, wind turbines, and other equipment. The high accuracy and reliability of bearings required by these machines can be well-met with outer spherical bearings. Their ability to endure high-speed rotation and complex loads ensures the efficient operation and long-term stability of the equipment.
In addition to the above industries, outer spherical bearings are widely used in textile machinery, food processing machinery, printing machinery, logistics and transportation equipment, steel, and metallurgical equipment, and other fields. These machines demand heavy loads and high-speed rotation, making outer spherical bearings an ideal match for such applications.
